ctrl+q copy-from-output stopped working after recent update

Previously, pressing ctrl+q would show a "ctrl+q to copy" prompt that allowed copying code blocks/snippets from Claude's responses. This worked reliably until a recent update.

Now ctrl+q does nothing — no prompt appears, no copy happens.

• Version: 2.1.50
• OS: Fedora Linux (kernel 6.18.9-200.fc43.x86_64)
• Keybinding config: ctrl+q is mapped to chat:snippetPicker in ~/.claude/keybindings.json

Expected: ctrl+q opens a picker to copy code blocks from assistant output
Actual: Nothing happens

This was a very useful feature — much better than mouse-selecting in a terminal. Would appreciate it being restored.
